Description: Thallus crustose, episubstratic, rimose-areolate, 0.1-0.2 mm thick, consisting of 0.2-0.5(-0.8) mm wide, dark grey, flat, angular areoles developing on a black hypothallus, often delimited by a black prothallus. Cortex c. 10 µm thick, dirty grey in upper part, overlain by a c. 10 µm thick epinecral layer; medulla white to brown in lower part, I-. Apothecia lecideine, black, rounded to most often angular or irregular in outline, 0.3-0.7(-1.2) mm across, at first immersed, later slightly protruding, with a flat to finally convex, more or less rugose disc, and a thin, persistent proper margin. Proper exciple grey-brown, green-grey or dark grey in outer part, pale grey-brown within; epithecium dark green or greenish brown, 15-25 µm high, N+ purple; hymenium colourless or pale green in upper part, 50-65 µm high, I+ blue; paraphyses mostly simple, almost not anastomosing, strongly coherent, c. 2 µm thick at mid-level, the apical cells 3-4 µm wide, without a dark cap; hypothecium brown to dark brown, 200(-400) µm high. Asci 8-spored, clavate, tapering at apex into a narrow apical dome, not or weakly I+ blue but ascus apex surmounted with a strongly K/I+ blue cap. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, 9-13(-14) x 6-9(-10) µm, thick-walled. Pycnidia black, immersed. Conidia ellipsoid-oblong, 3.5-4 x c. 1 µm. Photobiont chlorococcoid, the cells 10-13 µm wide. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on steeply inclined surfaces of wind-exposed, hard siliceous rocks in upland areas.
